WILLIAM H. COUGI-LIN, OF WORCESTER, MASSACHUSETTS.

INJECTOR-CONDENSER.

SPECIFICATION forming part of Letters Patent No. ?21,158, dated February 24, 1903. Application filed July 30, 1902. Serial No. 117`,620. (No model.)

To all whom it nay ocnoern:

Be it known that LWILLIAM H. COUGHLIN, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Means for Taking Boiler Feed- Water from the Discharge-'Pipes of Injector Steam-Condensers, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same. i

The object of my present invention is to provide, in connection with the discharge-pipe of a jet or injector steam-condenser, a simple, inexpensive,'and efficient means for taking a feed-water supply therefrom, se'parating the grease' or oil from the condensation-water, and obtaining hot pure water for feeding to steam-boilers.

The nature of my invention consists in providing, in combination with the dischargepipe in an injector-condenser, a Supplementary pocket, well device, 'or depending annexed chamber having its interier upper part in full communication with the interior of said discharge-pipe at a position between the injector-nozzle and the hot-wellor place of discharge and connecting with the lower part of said pocket or chamber the draft-pipe through which the boiler feed-water is taken,

said feed-water being drawn from the surplus hot condensive flow passing down from the condenser injector-nozzle, as more fully hereinafter explained.. v

In the drawings, Figure l represents an elevation view of an injector-condenser plant, illustrating the nature of my invention as applied in combination therewith and Fig. 2 is avertical section of my device for taking feedwater from the injector discharge-pipe.

In referring to the drawings, A indicates the condenser injector-nozzle; B, the watersupply pipe therefor and through which in practice cold water is delivered by a pump or other suitable means (not shown) attached to the end b in any convenient manner.

C indicates the 'exhaust-steam pipe from the engine E. A i v F indicates the hot-well into which the discharge enters, and 'G the hot-well overfiow;

all of which parts are Well known in their structure and mode of operation, the steam from the exhaust being condensed by the inflow of Water at the injector-nozzle A, the hot oily condensation fiowing down the dischargepipeD to the hot-well and exit overflow. The height of the discharge-pipe is some thirty- 'two feet (more or less) as employed in usual practice.

In my invention I provide the dischargepipe D with a lateral offset inclined section or member 3 at some convenient position between the injector A and hot-well F, and in full connection with such offset portion I arrange a depending pocket or annexed chamber 5, some three feet (more or less) in'length 'and preferably of about the same diameter as ,the discharge pipe, the pocket preferably forming a vertical sinkor Well in the line of said pipe. To the bottom or lower end 6 of this pocket-chamber 5 I connect the smaller draft-pipe 7 ,that leads to the boiler feed-pump P, and from the pump to the boiler or boilers to which feed-wateris to be supplied there extends the feed-pipe 9. The diameter and 5 are made considerably greater than that of the feed draft-pipe 7. i

In the operation the flow of water from the injector-nozzle, together with-the condensed steam and containing more or less grease or oil, passes down through the discharge-pipe D, the pocket or chamber being thereby kept constantly filled, while the greater quantity passes across the mouth of the pocket on its way to the hot-well or outfiow-exit. The liquid in the pocket being comparatively quiet, the grease or oil therein separates from the Water and, rising to the top of the chamber, is continually carried away by the flow in the ;discharge-pipe D, so that only hot pure water enters the bottom pipe 7 and' passes to the feed-pump P and to boilers by way of the pipe 9.

As advantageous results incident to this invention it will be 'noticed that I am enabled to take water for boiler-'feed purposes direct from an injector-condenser discharge, to draw out such feed-water near the' point where the maximum degree of heat for return to the boiler, also efiecting the separation of the cross-sectional area of the chamber or pocket IOO condensation is effected, thus utiliz ing the grease or oil from the feed-water in a simple and efficient manner and the constant discharge of the oil therefrom by the normal operation of the condenser flow. The means' for producing these results is simple and comparatively inexpensive for the purpose contemplated.

What I claim as of my invention, and desire to secure by Letters Patent, is

1. The combination with the disoharge-pipe from the nozzle of an injector-condenser, of a pocket at the side thereof forming a downward chamber with its upper end internally opening into said dischargepipe, and the boiler feed-pipe leading from the lower part of said chamber, for the purpose set forth.

2. The combination,with the discharge-pipe in an injector steam-condenser, of means for taking feed-water separated from oil, from the hot condensing flow thei-ein; said means comprising a Water-sink pocket formed upon or connected with the side of the discharge-pipe and open thereinto at a position intermediate to the condenser-injector nozzle and hot-well.

3. In combination, With an injecto' steamcondenser, the discharge-pipe having an cifset therein below the injeotor-nozzle, a. depending pocket internally open at its uppe' portion into said discharge-pipe oifset as a branch of substantially similar diameter, and having at or near its lower end an opening of smaller diameter to which the bOiIer-feed-Supply pipe is connected.

4. A device for taking feed-water from a jet or injector steam-condenser, comprising an inclined oifset member for connection with the discharge-pipe between the condensernozzle and hot-well, said member provided with a depending pocket of greater area. than the feed-water pipe, and open at its top end into the discharge-passage, and the bottom of said pocket provided with means for connection with the feed-water pipe, substantially as set fol-th.

Witness my hand this 28th day of July,1902.
